SPECIFICATION forming part of Letters Patent No. 277,613, dated May 15,1883.

Application filed February 8, i883. (Model.) I

To all whom it may concern Be it known that I, RICHARD M. RocKEY, acitizen of the United States, residing at Nora, in the county of JoDaviess and State of Illinois, have invented certain new and usefulImprovements in Tops for Milk-Gans and other Vessels; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the annexed drawings, making a part ofthis specification, and to the letters and figures of `reference markedthereon. t

Figure l of the drawings is a top plan view of my invention; Fig. 2, alongitudinal vertical section, and Fig. 3 a detail view of the same.

This invention relates to certain new and useful improvements in tops'for milk-cans and other vessels, the object thereof being to providesuch a device as will be simple and inexpensive in its construction, andreadily adapted to the ordinary vessels of this description tothoroughly exclude the air, dust, and other foreign substances, and atthe same time preveut any leakage. These objectsI attain by theconstruction substantially as shown in the drawings, and hereinaftermore fully described and claimed.

In the accompanyingdrawings, A represents the cover of a milk-can orother vessel, having slotted ears a extending outwardly from its rim. Tothis top, upon its upper face, on a line with the center of the slottedears c, are pivoted horizontally-operatedcamsB,provided With grooves11,1ever-arms c, and notches d, said top having upon its under fac-e arim, e, which, in conjunction with its outer rim,f, forms au annulargroove, g, for the reception of suitable packing.

To the vessel is suitably connected a ring, C, having formed therewith np wardly-projecting hooked arms h, adapted to register with and enterthe slots of the ears c on the cover, this said ring G coming againstthe packing placed between the rims ef to form a tight joint.

When the covcrA is to be connected to the vessel the cans B are broughtinto the posib of the cams, thereby admitting ofthe cover being broughttightly down upon the ring of the vessel and prevented from slipping orlateral displacement; and these cams, being operated horizontallyinstead of vertically, are more certain in their action, and the groovesin said cams, forming a guide for the hooked ends ofthe arms upon thering,increase.their effectiveness.

It will be readily seen that a cover for milkcans or other vesselsconstructed according to the foregoing description is not only neat inits appearance, but also readily operated to secure a tight joint, andfrom the simplicity of its several operating parts oa-n be easily andquickly attached to or removed from the vessel, while at the sametimeit, having no intricate parts, can be thoroughly cleansed with butlittle trouble or exertion.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

l. Acover for milk-cans or other vessels, having slotted ears extendingoutwardly from its rim and horizontally-operated grooved cams, incombination with a vessel provided with upwardly-extending hooked arms,substantially asand for the purpose set forth.

y 2. In a milk-can or other vessel, the ring O, provided withupwardly-projecting hooked arms 7L, in combination with the cover A, hav

ing outwardly-extended slotted ears andwhorizontallybperatedgrooved'cams, substantially as and for the purpose specified.

3. In a top for milk-cans or other vessels, having slotted ears a, thecams B, pivoted on aline with the center of said ears, and pro-` videdwith grooves b to form bearin gs and guides for the upwardly-extendedhooked arms h of the ring C, substantially as shown and described.

4. A cover for milk-cans or other vessels,

having slotted ears c projecting from its outer rim, and apacking-groove, g, upon its under face, in combination with the pivotedhorizontally-operating cams B and ring C,formed with upwardly-extendinghooked arms 71:., substantiallyT as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses. 4 i
